Geothermal heat pumps Ground  Source Heat Pump /water to water heat pump   Energy saving and environment friendly product Daishiba water source heat pump utilizes free renewable energy from ground, consuming much less energy without direct CO2 emission. It is efficient and economical alternative to both fossil fuel boilers and air-conditioning system This system are free from the effect of climate, it can run at rough conditions with high COP. Compared with common electric heater or gas boiler, water source heat pump reduces costs more than 75%.   Flexible applicability DAISHIBA water to water heat pump series can be applied in the independent and small scale space, such as multilayer apartments, villas, restaurants and entertainment places etc. It has a wide rang of capacity selection, from 6KW to 50KW.   Heating function Connected to insulation water tank, it can offer warm water all year around. If connected to the fan coils or floor coil, it could heat air in winter.   Cooling function are optional Both heating only function and heating & cooling function are available, you can make a choice according to your requirement.   Convenient operation Microelectronics control, all temperature settings are set by manufacturer. System tests and adjusts water temperature automatically. All what user needs to do is just to press “ON/OFF ” button. System finishes the other operation automatically.   Excellent performance Adopt world famous components, and the best match of system design. Scroll compressor with high EER and low noise. High efficient heat exchanger insures the utmost using of system capacity. Professional air conditioner water pump insures smooth quiet operation.   Easy to install The system is designed with full consideration of insuring installation as easy as possible. Refrigerant circle is a sealed complete system finished by manufacturer. No needs for users to connect copper pipes or refrigerant charging. Hydraulic circle of system can be connected to hydraulic terminals by two tubes.   Operating protection System is designed with over voltage, under voltage, over load protection to insure safe operation. The microelectronics controller can start or switch off the machine by judging the water temperature. If the water temperature is lower than designed, the machine will be switch off to avoid freezing. The microelectronics controller can also supervise the status of components. Malfunction occurred would be transmitted to the controller and displayed through malfunction code.   Specification
